There is a long thread going on with no one can able to answer "why my CPU usage is 10-100% when i mine with GPU?"

I got a hunch that it may be CPU make.So created this poll.So far i rarely saw my 10-100% usage of pocblm in my pc.

Please vote which make, Intel or AMD CPU you use in your mining pc/laptop/... Also, you can post about your complete CPU details with OS details.

EDIT

I forgot to mention one thing, i too once got 15% cpu usage after reinstall. i also installed a software the day i started mining, i thinkGranola i already even made a post about it.Its free. Please try & see if, at least granola reduces cpu usage.

AMD Athlon 64 X2 3800+ running on Ubuntu 10.04 amd64. I'm running the CPU miner only on one core, because I end up with 100% CPU usage on the other core if I run pocblm

Out of curiosity I just booted Windows Vista Home 64 on the same maschine and installed pocblm. The CPU usage is between 0 and 3% Furthermore Windows outperforms Linux by the factor 10 (3.5 vs. 33 Mhash/s)

Dang! So is there ANY fix for this? This extra CPU load is just wasted electricity.

I used granola & after that i see 0 CPU usage.But that too didn't help ~anyone

How does this "granola" program fix this problem? How does that have any relation to this high cpu usage while mining problem? I do not want to undervolt (already did that) my cpu, nor underclock it, nor disable any of the cores. I just want the damn miners to stop chewing constantly 13% of each core for a total max cores of 2. So that's 100% cpu usage for one core relative to 8 hyper-threaded cores (i7 920).

I've explained this a few times now, in various threads... The reason poclbm takes high CPU is because there is no wait delay in between thread executions. It can be fixed with 2 new lines of code, and changing 1 line of code.

I'll be happy to explain. If you're interested, PM me.

You're quite sure this is JUST a poclbm problem? I recently switched to a new miner and it does the same thing.

Also guys let me be clear. I do not get 100% cpu usage across all cores. I get a constant 13% cpu usage PER miner process (regardless if its poclbm.exe or something else)

One of the developers of the new miner I'm using said that this is caused by ATI's OpenCL implementation.

experiencing a similar problem (100% cpu usage in one core) with 3 different gpu miners (poclbm/phoenix/diablo) on wife's nvidia 8600gt, windows7-32bit. since only some of us have this problem (and with different architectures and different windows versions) could it be the drivers, and/or some version of win7?

You get 13% usage because you have eight cores, and poclbm is only written to utilize one core. So, one core out of eight = around 13%. If you had a dual core CPU, for example, you'd get 50% usage per miner process.
